Here we discuss an introduction to Matlab Plot Legend with appropriate syntax and respective programming examples. Labels become very important when we plot multiple functions in the same graph. We also learned to set the ‘direction’ and ‘Name’ of the label box as per our needs.
Legend matlab how to#
We learned how to create labels in MATLAB plots and also how to achieve desired styles. Legend (,'Location','northwest')Įxplanation: As we can notice in the output, our label box is now named.
Legend matlab code#
All we need to do is pass the pre-defined code for the direction, as an argument. When I have a legend, and then add another plot to the graph, it is automatically added to the. Use the Peer field of the event data structure to access properties of the chart object associated with the clicked legend item. Learn more about r2017a, legend, autoupdate MATLAB. Legend function in MATLAB allows us to put our label in place of our choice. MATLAB automatically passes these inputs to the callback function when you click an item in the legend.

Next, what if we don’t want our labels to be on the top right but in some other place on the plot. Here, we can name our functions as per our needs.Įxplanation: Notice on the top right side of the plot, we have got the names of our functions. In addition to the above code, we will add the below-mentioned line:Īs we can see, we have passed the name of the functions as an argument to our legend function. You also can create a legend with multiple columns or create a legend for a subset of the plotted data. These examples show how to create a legend and make some common modifications, such as changing the location, setting the font size, and adding a title.
Legend matlab series#
Our initial code will be the same as in the above example Legends are a useful way to label data series plotted on a graph. Now, what if instead of ‘data1’ and ‘data2’, we want to have the name of the function as the label. Since nothing was passed as an argument to legend function, MATLAB created labels as ‘data1’ and ‘data2’. This is how our input and output will look like in MATLAB console:Įxplanation: As we can see in the above output, we have plotted 2 vectors and our legend function created corresponding labels. Our inputs A, B& C are first passed as arguments to the function ‘plot’.Īnd then we simply write ‘legend’ in our code to get the labels. Now to understand how ‘Legend’ works, we will first plot our input functions and then use the function ‘legend’. Bug and workaround in timeseries plot Matlab's internal hgconvertunits function has a bug that affects timeseries plots. Next, we will define B as the cos function of values of A and C as sine function of values of A Plot legend customization Matlab plot legends and their internal components can be customized using a variety of undocumented properties that are easily accessible.

We will define an increment of π/50 between these values. Let us understand the function with an example: Example #1įirst, we will define ‘A’ as a vector containing values between 2pi (π) and 3π. The function ‘legend’ will create labels like ‘data1’, ‘data2’, and so on. , L N), where L1, L2 and so on represents the respective labels.Įxplanation: This function will create a legend for each data series used in the plot, with descriptive labels.
